siimply marketing

A minimal marketing toolkit for indie founders. Just what works — AI skills you drop into Claude Code or Codex, focused guides, and one-tool-per-job working software.

Built as a Next.js 16 web hub AND a Claude Code workspace. Information lives in the web app (guides, skills, resources). AI skills + specialist subagents live in .claude/ for direct use from any Claude Code session opened against this repo.

What's inside

Information (web hub):

• /start-here — glossary (CAC, LTV, AARRR, ASO, PMF, ICP, NSM, MoM, churn, activation, CTR, MVP) + 5-step roadmap
• /guides — 14 opinionated guides incl. the flagship "promote a new mobile app" playbook, video marketing, marketing-on-autopilot, design automation
• /skills — 10 AI skills, downloadable as Markdown
• /resources — curated books / newsletters / communities / SaaS

Working tools:

• /tools/scheduler — IG + X multi-platform scheduler (official APIs, local-first)
• /tools/visual-builder — programmatic social-image generator (Next.js next/og)
• /tools/image-generators — curated catalog of widely-used AI image-gen services (Midjourney, ChatGPT, Gemini, Flux, Ideogram, Recraft, and more)
• /tools/page-capture — Chrome extension for capturing webpage content into draft posts

Claude Code workspace:

• .claude/skills/<slug>/SKILL.md — 10 marketing skills loaded into Claude Code automatically
• .claude/agents/<name>.md — 6 specialist marketing subagents (gtm-strategist, copywriter, aso-researcher, content-batcher, video-director, design-director)

Stack

Next.js 16 (App Router) · Drizzle ORM · better-sqlite3 · Tailwind v4 + hand-rolled shadcn-style components · next/og for image generation. Local-first SQLite at data/app.db.

Setup

npm install
npm run dev      # http://localhost:3000

SQLite auto-creates and auto-migrates on first run.

For the scheduler to actually post, see .env.example and connect a Meta and/or X developer app. For the AI features in skills, set AI_GATEWAY_API_KEY. For the Chrome extension, generate an APP_API_KEY.

Use as a Claude Code workspace

Open this repo in Claude Code. The skills and subagents are auto-discovered:

# In a Claude Code session inside this repo:
/agents              # lists the 6 marketing subagents
# Talk to one:
"Hand off to gtm-strategist: I'm launching a fitness app for runners. What should I do first?"

# Or invoke a skill directly:
/skill icp-writer

Use with Codex / other Anthropic SDK clients

The skills under public/skills/*.md are platform-agnostic Markdown with YAML frontmatter. Copy them into your client's prompt directory. The .claude/skills/<slug>/SKILL.md form is specific to Claude Code.

What this project deliberately doesn't do

• Auto-DM / auto-comment / auto-follow on social platforms (violates ToS)
• Webhook-driven live event handling (would need always-on hosting; cut for simplicity)
• Personal IG account automation (Meta API requires Creator/Business — see /guides/switch-to-creator)
• Video tweet uploads (chunked upload pipeline, out of scope for MVP)

Useful commands

npm run dev          # start Next.js
npm run build        # production build
npm run db:generate  # generate a new migration after schema edits
npm run db:studio    # Drizzle Studio against your local DB
